Seuraava Laskennallisen kemian seminaari järjestetään keskiviikkona 22.2.2023 klo 10 Zoomissa.
Puhuja: Vivek Sharma, Helsingin yliopisto
Aihe: Electronic and protonic currents of life
Biological energy (ATP) is efficiently produced in cells by a pathway called the electron transport chain. Electron transfer reactions are strongly coupled to proton transfer reactions, which drives the translocation of protons across the biological membranes. An established proton electrochemical gradient drives the synthesis of ATP, which serves for numerous biological functions. In this talk, I will discuss how protein architecture in the electron transport chain, biological membranes and solvent water catalyze electron and proton transfer reactions to generate energy. The methods applied to study these processes, classical molecular simulations and quantum chemical calculations, will be discussed.
